The Great Search: Quad Microphone I2S ADC from Echo Dot Teardown #TheGreatSearch #DigiKey #Adafruit @DigiKey @Adafruit
The Great Search is a new series of videos focused on searching the Digi-Key catalog to narrow down to the parts you want to buy. This week (video):
While checking out an Echo Dot teardown, we spotted a quad microphone ADC that has some nifty features. How can we fit 4 channels into a stereo I2S connection? We looked at it and also found a sister chip that doesn’t even require I2C configuration! These chips would be great for far-field and voice control projects.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
